WASHINGTON - US President Donald Trump released the long-promised $1.5 trillion infrastructure initiative on Monday, aiming to rebuild the nation's outdated roads, railways and other public works.

The 53-page document details Trump's plans of how to fund the investments, shorten project permitting time, remove regulatory barriers, help rural areas, and improve worker training.

"Our Nation's infrastructure is in an unacceptable state of disrepair, which damages our country's competitiveness and our citizens' quality of life," Trump said in a letter to the Congress.
